SPECIFICATION forming part of Letters Patent No. 382,116, dated May 1,'1888.

Application filed Januaryi, 1888. Serial No. 261,597. (No model.)

To all whom, 0' may concern.-

Be it known that I, WILLIAM THOMAS SLICER, a citizen of the UnitedStates, residing at Colora, in the county of Cecil and State ofMaryland, have invented certain new and useful Improvements in Devicesfor Setting Saws; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to devices for use in setting saws, and has for itsobject to generally improve upon the construction of this class ofappliances.

To this end, and to such others as the invention may relate., the sameconsists in the peculiar,construction'and in the novel combination,arrangement, and adaptation of parts, all as more fully hereinafterdescribed, shown in the accompanying drawings, and then speciticallydefined in the claims.

In the drawings, Figure l is a side view of a saw-set constructed inaccordance with my invention. Fig. 2 is a central longitudinal sectionthrough the same, and Fig. l3 is a central transverse section on thelinexx of Fig. 1.

Reference being had to the details of the drawings, A represents themain frame, which is provided at one of its ends with a fixed handle, B.lThe shaft is provided, at a point substantially at its longitudinalcenter, with a downwardly-curved portion, C, and pivoted vupon theraised extension a upon the upper face of the shaft and adjacent to thecurved portion is the horizontal wheel D, the outer periphery of whichis beveled and provided with a series of notches, as shown.

E is a casting adapted to lit over and move freely upon the squaredportion 7s of the shaft upon the side of the curved portion oppositethat upon which the wheel D is journaled.

D2 is a wheel in all respects similar to the wheel D, and is pivotedupon the upper face of the extension a of the casting E. lIhe relativepositions of the wheels D and Dl are such that when the casting E is inposition upon the frame A the upper faces of the wheels will be in thesame horizontal plane, and when moved into contact, as hereinafterdescribed, the notches formed within the beveled periphery of one of thewheels will mesh with those of the opposite wheel.

Ezis an extension of the casting E, and is in the form of a collaradapted to fit over and move freely upon the rounded portion d of theframe A, and when the wheels are in contact this collar will abutagainst the shoulder d2.

F is a raised portion or flange extending around the outer face of thecollar E. rIhe handle B2 is provided with a central longitudinalopening, I, which is extended a suitable distancewithin the handle toreceive the screwthreaded extension e of the main frame, as shown.

I2 is an internally-screw-threaded casting, provided at its inner endwith arms gg, which arms are formed upon their-adjacent inner faces witha groove adapted to embrace the fiange F upon the collar E2. 'Ihe outerend of the casting I2 is provided with extensions K K2, within which issecured the end of the handle BZ.

H is a guide or gage for regulating the vertical position of the saw.This gage is made of a single casting, the bifurcated portion of whichis adapted to embrace the curved portion of the shaft and to movevertically within suitable guides formed upon the sides of the same.Each of the arms H2 of the gage H is provided at its upper end with ahorizontal extension, H", and the gage is made vertically adjustable bymeans of a set screw, as will be readily understood.

From the foregoing description the operation of the device will bereadily understood. The wheels D D, having been separated by turning themovable handle B2, ,the saw to be operated upon is placed between thewheels with the teeth of the saw resting upon the up per faces of thearms H3 of the gage. The gage is then vertically adjusted to the properpoint by manipulating the set-screw J, after which the wheels arebrought into close contact with the saw-teeth by turning the. handle B2,and by passing the device along the line of the sawteeth the teeth are,properly set or adj usted by a single movement.

Having thus described my invention, what I ICC claim to be-new, anddesire to secure by Letl ters Patent, is-

l. The combination, with the bifurcated main frame and thesetting-Wheels journaled one upon each side of the bifurcation, of thebifurcated gage on said shaft and adj ustable in the bifurcationparallel with the axes of said Wheels, substantially as described.

2. The combination, with the main frame and the setting-Wheels journaledthereon, of the guides on said main frame, the gage having bifurcatedshank, the arms of which Work in said guides, and the adj usting-screwpassed through said shank and engaging a screwthreaded hole in the mainframe, substantially as described.

3. The combination, with the main frame provided with a setting-wheel,of the casting E, carrying a setting-wheel, and a casting, I2, engagingsaid casting E and adjustable lengthwise on said frame, substantially asand for the purpose described.

4. The combination, with the main frame provided with a setting-wheel,and having squared port-ion, as described, and the casting carrying thesetting-wheel and having arms engaging said squared portion, and acollar having a flange, of the lcasting I2, engaging the ange of thecollar and adj ustablel on the frame, substantially as and for thepurpose described.

5. The combination, with the main frame provided with a setting-Wheel,and having squared portion k and screw-threaded portion e, of a castinghaving depending arms E embracing said squared portion, a collar slidingloosely on the frame and having a iiange, F, a setting-wheel journaledon said casting, and a handle provided with a casting having arms gengaging the flange of said collar, and internally threaded to engagethe threaded portion of the frame, substantially as and for the purposedescribed.

In testimony whereof I affix my signat-ure'in presence of two Witnesses.
